Payroll management is a critical function for any business. While often overlooked, errors in payroll can lead to significant legal and financial consequences for employers.
In Australia, the Fair Work Act 2009 and related legislation set out strict requirements for handling payroll errors, including underpayments and overpayments.
This guide outlines the steps employers must take to manage payroll errors effectively, ensuring compliance with Australian law and fostering a positive workplace environment.
Key Takeaways
- Promptly identify and correct payroll errors to comply with the Fair Work Act 2009.
- Transparent communication with employees is crucial when addressing payroll mistakes.
- Employers must obtain written consent for any deductions from wages, even in cases of overpayment.
- Maintaining accurate payroll records for at least seven years is a legal requirement.
- Preventative measures, such as regular audits and staff training, can minimise payroll errors.

Understanding Payroll Errors
Payroll errors can occur due to various reasons, including:
- Misinterpretation of awards or enterprise agreements.
- Data entry mistakes.
- System faults or outdated payroll software.
- Regardless of the cause, employers are legally obligated to rectify these errors promptly to ensure employees receive their correct entitlements.
Legal Obligations for Employers
Correcting Underpayments
Under the Fair Work Act 2009, employers must rectify underpayments as soon as they are identified. Failure to do so can result in penalties imposed by the Fair Work Ombudsman.
As of 1 January 2025, intentional underpayment of wages is a criminal offence, with penalties including fines of up to $7.825 million for companies and imprisonment for individuals.
Handling Overpayments
Overpayments often occur due to clerical errors or misinterpretations of employment contracts. Employers cannot unilaterally deduct overpaid amounts from an employee’s wages without their written consent. Instead, they must negotiate a repayment plan with the employee, ensuring the terms are reasonable and documented in writing.
Record-Keeping Requirements
Employers must maintain accurate payroll records for at least seven years. These records should include details of hours worked, wages paid, and any corrections made. Non-compliance with record-keeping obligations can result in significant penalties.
Steps to Manage Payroll Errors
Immediate Identification and Correction
- Investigate the cause of the error promptly.
- Calculate the correct amount owed to the employee.
- Rectify the error without delay to ensure compliance with legal obligations.
Transparent Communication
- Notify affected employees in writing about the error.
- Provide details of the mistake, corrective actions taken, and the timeline for rectification.
- Engage in open discussions to agree on repayment terms in cases of overpayment.
Seeking Professional Advice
If there is uncertainty about payroll obligations, employers should seek advice from legal professionals or consult the Fair Work Ombudsman.

Preventative Measures
Regular Audits
Conduct periodic reviews of payroll processes to identify and rectify discrepancies before they escalate.
Staff Training
Ensure payroll staff are well-trained and up-to-date on current employment laws, awards, and enterprise agreements.
System Upgrades
Invest in reliable payroll software that complies with Australian standards and reflects legislative changes.
Voluntary Small Business Wage Compliance Code
Small businesses are encouraged to adhere to this code, which may provide protection from criminal prosecution in cases of unintentional underpayment.
